Statistics and other data on overdoses, including mortality estimates. Overdoses from all causes are examined, including alcohol, cocaine, and methamphetamine, in addition to heroin, fentanyl, and other opioids. Includes a subsection on naloxone, the opiate antagonist that can immediately reverse an opioid overdose.

Cocaine Toxicity or Overdose

(Cocaine Toxicity or Overdose) "An overdose may cause severe anxiety, panic, agitation, aggression, sleeplessness, hallucinations, paranoid delusions, impaired judgment, tremors, seizures, and delirium. Mydriasis and diaphoresis are apparent, and heart rate and BP are increased. Death may result from MI or arrhythmias.

Key Factors Underlying Increasing Rates of Heroin Use and Opioid Overdose in the US

"A key factor underlying the recent increases in rates of heroin use and overdose may be the low cost and high purity of heroin.45,46 The price in retail purchases has been lower than $600 per pure gram every year since 2001, with costs of $465 in 2012 and $552 in 2002, as compared with $1237 in 1992 and $2690 in 1982.45 A recent study showed that each $100 decrease in the price per pure gram of heroin resulted in a 2.9% increase in the number of hospitalizations for heroin overdose.46"

Alcohol Poisoning Deaths in the US, 2010-2012

Alcohol Poisoning Deaths in the US, 2010-2012: "On average, 6 people died every day from alcohol poisoning in the US from 2010 to 2012. Alcohol poisoning is caused by drinking large quantities of alcohol in a short period of time. Very high levels of alcohol in the body can shutdown critical areas of the brain that control breathing, heart rate, and body temperature, resulting in death. Alcohol poisoning deaths affect people of all ages but are most common among middle-aged adults and men."

Medical Cannabis Laws and Opioid Overdose Mortality Rates

"In an analysis of death certificate data from 1999 to 2010, we found that states with medical cannabis laws had lower mean opioid analgesic overdose mortality rates compared with states without such laws. This finding persisted when excluding intentional overdose deaths (ie, suicide), suggesting that medical cannabis laws are associated with lower opioid analgesic overdose mortality among individuals using opioid analgesics for medical indications.

Lower Opioid Overdose Mortality Rates In States With Medical Cannabis Laws

"Although the mean annual opioid analgesic overdose mortality rate was lower in states with medical cannabis laws compared with states without such laws, the findings of our secondary analyses deserve further consideration. State-specific characteristics, such as trends in attitudes or health behaviors, may explain variation in medical cannabis laws and opioid analgesic overdose mortality, and we found some evidence that differences in these characteristics contributed to our findings.

Polydrug Involvement in Pharmaceutical Overdose Deaths in the US

Polydrug Involvement in Pharmaceutical Overdose Deaths in the US: "Opioids were frequently implicated in overdose deaths involving other pharmaceuticals. They were involved in the majority of deaths involving benzodiazepines (77.2%), antiepileptic and antiparkinsonism drugs (65.5%), antipsychotic and neuroleptic drugs (58.0%), antidepressants (57.6%), other analgesics, antipyretics, and antirheumatics (56.5%), and other psychotropic drugs (54.2%).

Drug Overdose Deaths in the US, Polydrug Use, and Involvement of Prescription Pharmaceutical Drugs

"Of the 36,667 drug overdose deaths with at least one mention of a specific drug, 52% mentioned only one specific drug (18,931 deaths), 26% mentioned two (9,351 deaths), 12% mentioned three (4,521 deaths), 6% mentioned four (2,041 deaths), and 5% mentioned five or more (1,823 deaths). Among drug overdose deaths with at least one mention of a specific drug, the average number of specific drugs mentioned was 1.9.

Cost-Effectiveness of Naloxone Distribution

"Naloxone distribution was cost-effective in our base-case and all sensitivity analyses, with incremental costs per QALY [Quality-Adjusted Life-Year] gained much less than $50 000 (Table 2 and Appendix Figure 3, available at www.annals.org; see Appendix Table 3, available at www.annals.org, for detailed results of selected analyses). Cost-effectiveness was similar at starting ages of 21, 31, and 41 years; the greater QALY gains of younger persons were roughly matched by higher costs.

Benefits from Naloxone Distribution

"Naloxone distribution to heroin users would be expected to reduce mortality and be cost-effective even under markedly conservative assumptions of use, effectiveness, and cost. Although the absence of randomized trial data on naloxone distribution and reliance on epidemiologic data increase the uncertainty of results, there are few or no scenarios in which naloxone would not be expected to increase QALYs [Quality-Adjusted Life-Years] at a cost much less than the standard threshold for cost-effective health care interventions.
